The Synthesis of Medium-Sized Cyclic Lactams by the Intramolecular Friedel-Crafts Cyclization of Isocyanates. Formation of Novel Pyrazolobenzolactams

A series of 4-ω-phenylalkyl substituted-1H-pyrazol-5-amines has been synthesized from the corresponding α-acetylphenylalkanenitriles and methylhydrazine.They were converted into the corresponding 5-isocyanates and cyclized under Friedel-Crafts conditions
